This distinction reflects success in a number of RETC tests that are significantly more rigorous than the IEC standard, demonstrating the excellent reliability, oustanding performance and superior quality of
As a leading independent test laboratory for photovoltaic and renewable energy products, RETC publishes the annual PVMI report with a focus on technology and quality indicators, including three essential module attributes: reliability, performance and quality.
During product reliability tests, Trina Solar Vertex 670W series modules scored high in the DH2000 damp heat test, the DML sequence and the TC600 thermal cycle test. The DML sequence recognizes manufacturers whose modules degrade less than 1% after being subjected to dynamic mechanical loading followed by 50 thermal cycles and 30 humidity-freeze cycles. From multiple rigorous mechanical load tests in the laboratory to practical applications in projects worldwide,
In performance tests, Trina Solar scored well in PAN file characterization, LID resistance and LeTID resistance. The 670W series modules achieved less than 0.5% power loss after 486 hours of LeTID test exposure, outperforming other modules. In the high performance in LID resistance test, Trina modules achieved a top 10 ranking among all modules tested based on LID performance ratio. For the PAN file characterization test, Trina modules produced a top performance ratio greater than 85%. The modules also performed well in the quality test sequence.
This latest recognition adds to a growing list of accolades for Trina in recent months. In May,
